XL When we find a like resemblance of genera and species 
between 'l'emperate zone provinces in opposite hemispheres that 
are almost exact antipodes, as in the case of Great Britain and 
New Zealand, we have no choice of hypotheses left. We must 
appeal directly to creative agency for the peopling of the New 
Zealand seas as well as the British, and see in both, like wis- 
dom, and a like adaptedness of life to physical nature. "T'he 
Paleemon affinis of the New Zealand seas is hardly distinguish- ! 
able from the common P. squilla of Europe, and 1s one example 
of this resemblance. 1t may not be an identity ; and on this ac- 
count it is a still better proof of our principle, because there is . 
no occasion to suspect migration or any other kind of transfer. 
It is a creation of species in these distant provinces, which are 
almost identical, owing to the physical resemblances of the seas ; 
and it shows at least, that a very close approximation to, identity 
may be consistent with Divine Wisdom. 
'l'he resemblance of the New Zealand and British seas has 
been remarked upon as extending also to the occurrence in both 
of the genera Portunus and Cancer. [tis certainly a wonderful 
fact that New Zealand should have a closer resemblance in its 
Crustacea to Great Britain, its antipode, than to any other part of 
the world—a resemblance running parallel, as we cannot fail to 
observe, with its geographical form, its insular position, and its 
situation among the temperate regions of the ocean. Under 
such circumstances, there must be many other more intimate re- 
semblances, among which we may yet distinguish - the special 
cause which led to the planting of peculiar British genera in this 
antipodal land. 
'l'he close resemblance in species and genera from Britain and 
New Zealand, and from Japan and the Mediterranean, and the 
actual identity in some species among the latter, proves therefore 
that, as regards the species of two distant regions, identity as. 
well as resemblance may be attributable to independent creations, 
these resemblances being in direct accordance with the physieal | 
resemblances of the regions. As this conclusion cannot be avoid- - 
ed, we are compelled in all cases to try the hypothesis of migra- 
tion by considering something beside the mere possibility of its | 
having taken place under certain assumed conditions. 'Tlhe pos- | 
sibility of independent creations is as important a consideration. 
After all the means of communication between distant provinces 
have been devised or suggested, the principle still comes up, that 
itis in accordance with Divine Wisdom, to create similar and | 
identical species in different regions, where the physical cireum- 
stances are alike; and we must determine by special and thor- . 
ough investigation, whether one or the other cause was the ac- - 
tual origin of the distribution in each particular case. "'lhusit 
must be with reference to the wide distribution of species in the 
49 Geographical Distribution of Crustacea.
